I understand completely what you mean and I discussed the scaling down you describe in some draft versions, but I really don't like proposals that include too many changes where a voter may be forced to take the good with the bad or vote against something they like because there is something else included they don't, so I removed it again.
My suggestion (to you and others who enjoy these tournaments) would be to wait a bit how things shake out, see which tournaments regularly get cancelled and then introduce a new proposal to modify their parameters. I personally would vote for such tournaments to be modified so they can happen regularly under the 75% participation rule with a modified and reduced prize pool (due to the earlier cutoff). That said, I believe many would rather want to see a complete rework of tournaments (me among them) so I don't know how much traction such a proposal would get.
